我输入命令“sudo service lightdm stop”，还是无法安装Nvidia驱动NVIDIA-Linux-x86_64-367.27.run，错误信息是需要stop X server，请问如何安装驱动？
答案1
您可以尝试按照说明添加 ppa ppa:graphics-drivers/ppa这里并使用 apt-get 或“附加驱动程序”进行安装。
答案2
Vulkan 就绪 nvidia 驱动程序：（NVIDIA-Linux-x86_64-367.27.run）只要您的显卡出现在此列表中，就可以在 ubuntu 16.04 上正常运行： https://developer.nvidia.com/vulkan-driver
当我直接从 nvidia 下载安装驱动程序时，它锁定了我的计算机，因此我尝试了这个方法，效果很好：
删除所有现有的 nvidia 包：
dpkg -l|grep nvidia
sudo apt-get remove --purge nvidia*
dpkg -l|grep nvidia
然后添加这个 repo
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
sudo apt-get upgrade
重启后你将进入 nouveau，进入设置->软件和更新->附加驱动程序...选择 Nvidia 367.35（最高数字）...再次重启后你就可以确认你现在可以在 ubuntu 16.04 上运行 Vulkan 了
dpkg -l|grep nvidia
ii nvidia-367 367.35-0ubuntu0~gpu16.04.1 amd64 NVIDIA binary driver - version 367.35
ii nvidia-opencl-icd-367 367.35-0ubuntu0~gpu16.04.1 amd64 NVIDIA OpenCL ICD
ii nvidia-prime 0.8.2 amd64 Tools to enable NVIDIA's Prime
ii nvidia-settings 367.35-0ubuntu0~gpu16.04.1 amd64 Tool for configuring the NVIDIA graphics driver
现在你可以安装 Vulkan... 之后这确认一切正常
